Bridge Width

Bridge Width is the shortest distance (in millimeters) between your two lenses.

Temple Length

Temple Length is the length of the temple to its temple tip, including the bend that sits on your ear.

Due to the different measurements methods, the measurements printed on the inside of the temple arm may vary from those showing on our website.

RX RANGE

Rx is customarily part of the superscription of a prescription, for a patient to purchase a prescription drug from a pharmacist.
It can only be made in certain prescriptions. This is an approximate range based on the spherical (SPH) value.
If you have astigmatism (CYL) in your prescription, this range may be further limited.
Please enter your prescription on the order page to check whether the glasses are suitable for you.

PD RANGE

Pupillary Distance (PD) is the distance, in millimeters, between the center of one pupil to the center of the other.
The PD is needed to manufacture your eyeglasses because it determines the exact optical center of the lens, which is the point where you look through the lens.
PD is especially important for manufacturing progressive lenses.

Once you have your PD, you can upload your photo to the Frame Fit tool and begin trying on glasses.
The Frame Fit tool allows you to see exactly what the glasses look like on you and how well they fit the size and shape of your face.
If you don’t have your PD, you can find out how to measure it
here.

PROGRESSIVE

This refers to the lens design which includes three fields of vision, without lines, and is sometimes referred to as a "no-line multi-focal".

In a progressive lens, the shape of the corrected part of the lens is approximately that of a funnel or a mushroom.
The top portion is for distance-vision, narrowing to the lower middle for mid-range, finally to the bottom portion for the near-vision or reading.
The reading area is expected to be smaller than the distance area. People sometimes prefer a single-vision lens for extended reading or up-close work.

The lens height for a progressive lens must be 33mm or greater. We recommend a taller lens for more comfortable wear, but the minimum lens height is 33mm.
If this frame has a lens height smaller than 33mm, a different frame must be chosen for progressive lenses.

Single Vision lenses are the standard eyeglass prescription. These glasses are for one field of vision across the entire lens. Correct one field of vision (near, intermediate, or distance).

Progressive

Progressive lenses correct near, intermediate and distance in one lens. In a progressive lens, the shape of the corrected part of the lens is approximately that of a funnel or mushroom. The top portion is used for distance-vision, the middle portion (corridor) for mid-range vision, and the bottom portion for the near-vision or reading.

Non-prescription

Non-prescription lenses offer protection and style with no vision correction.

Sports glasses prescription type

Zeelool offer both sports glasses and prescription sports glasses with single vision and progressive.

SPH (Sphere)

Spherical error, or overall power of lens is the basic part of your prescription.
A (+) means you have trouble seeing near, and a (-) means you have trouble seeing things faraway.

CYL (Cylinder) & Axis

A cylinder value indicates astigmatisms or perpetually blurry vision. Axis—measured between 1 and 180°— tell us the orientation of the astigmatism.

ADD (Addition)

This number indicates the additional magnification that is added to the distance prescription to get the reading portion of the lens in a multi-focal prescription.

PRISM

We can process prism prescriptions to correct eye orientation.

PD

PD (PUPILLARY DISTANCE) is the distance between your two pupils in millimeters. If there is no PD on your prescription, checking with your eye doctor is recommended, or

ADD corrects near vision for reading. If you see one number listed for ADD, use it for both eyes.

Sunglasses lenses

Protect your eyes from the sun and harmful UV rays in style. Choose a lens from one of the following lens options. At Zeelool,
sunglasses lens options including basic UV protection lenses, color tint, and prescription sunglasses.

Photochromic lenses are optical lenses that darken on exposure to specific types of light of sufficient intensity. In the absence of activating light, the lenses will return to clear state.

Color Tint

A lens tint is a permanent color in the lens used for either fashion or as sunglasses. Tint brightness and density may appear slightly different on each computer screens and mobile devices.

Solid lens tint meaning the color and strength of the tint will be the same from the top to the bottom of the lens. Gradient tint meaning the color is darker at the top and grades down to a lighter tone at the bottom of the lens.

Anti-reflective coating

super hydrophobic coating. An AR coating is a layered metal oxide coating applied to both sides of the lens that greatly
reduces both the internal and external the reflections on the lens surface while allowing more light through the lens.

Super Hydrophobic coating

Super Hydrophobic coatings have all the properties of a regular AR coating, plus the added benefit of a water resistant coating that repels dirt and water, and is easier to clean.
